Thanks for the nice explanation. At 10:30 around, it was mentioned that ship_id dets captain_id (this assumes a ship is associated with a captain, else a ship can have mul captains). In that case captain_id also should det ship_id (as a ship always associated with captain), but at 10:38 its given that captain_id does not det ship_id. Some pls clarify. Thank you....

Hi, here (10:17) just like we argued that Captain_id cannot determine the ship_id, cuz one ship can have multiple captains assigned to it, why can't we think that ship_id cannot determine the captain_id or captain_name? (09:42)
I'm kinda stuck in that point.
I got the answer as "ship_id--->shipname"; indicating it's only the shipname that can be identified by ship_id. can u plss explain?

this isn't easy or simplified. it sounds like you're reading out of a textbook.
